C.6.18.1 Explosion

To convert the old explosion particle system to new particles you
can use a sphere emitter with a very small radius and with particle
placement in center. Set a very small duration and a high emission rate
so that all particles will appear to be created at once. Using
a linear color effector you can obtain the fading of the particles (use
either alpha mixmode or add depending no the kind of fading you want).
Here is an example of how the old explosion can be emulated using
the new particle system (in code): Note that this is not an attempt to
make a realistic or even nice looking explosion. It is just an attempt
to emulate the ugly old explosion particle system from the past:
